TOOL.

Specification of Letters Patent.

Patented Doc. to, 191.3.

Application filed May 2, 1910. Serial No. 558,975.

. of detachable pneumatic or other resilient ltl tlli

tires and detachable or separable rims. Tools of this class are commonly known as tire tools, although they are used not only for detaching the tire itself from the rim, but are designed to be used for assembling the various parts of a separable rim, tor

example, as illustrated in the drawings accompanying this specification, or for the manipulation of certain forms of demountable rims.

in the accompanying drawings, which form a part of this specification, Figure l is a perspective view of a section of a tire and rim and of my improved tool, showing its mode of operation when used to draw to ether the split flange of a two part sepaafile or so-called quick-detachable rim; Fig. 2 is a view showing the two parts of the tool separated; Fig. 3 is a detail view partly in section of the end of one of the tool parts illustrating the construction of the reversible plug; Fig. t is a cross section oi a portion of a rim and detachable flange showing a mode of using my device for removing the detachable flange.

Referring to the drawings in detail, the tool comprises a pair of crossed bars 1 and 2 pivoted together in any suitable manner as by means of a pin 3 projecting from one of the bars through an opening d in the other bar. The pin 3 preferably has a lshaped head 5 which may be passed through the opening 4: when the bars are turned to such a position that the longer axis of the head corresponds with the greatest diameter of the opening t, the head preventing the separation of the bars when they are turned to any otherposition. The portion of the bar 2 about'the opening 4 is preferably recessed, as indicated at 6, to receive the "Tr-shaped head. The shoulder arms 7 of the bars are preferably turned outwardly beyond the point where the bars are pivoted, the ends of these arms being formed into internally threaded eyes 8. Thread ed plugs 9 screw into these eyes, each plug being provided with a faced portion 10, or other suitable means, by which it may be 60 turned when being screwed into its eye, or withdrawn therefrom.

Projecting from the ends of the pin are pins or studs 11 and 12, preferably 0 different characteristics, such as diameter, as W shown in the drawings, or it may be of different lengths or shapes, in order to make them suitable to engage ditlerent types of rims or ditlerent parts of the same rim. [is shown in the drawings, the pins have dif- W ferent diameters, Figs. 1 and 2 showing the plugs inserted with the small pins 12 projectmg in such manner as to be engaged with holes in the ends of the split tire retaining flange on the rim 21. Fig. 3 W shows how the plugs may be reversed to bring the pins 11 of larger diameter into operative position, thereby rendering the tool suitable for use with a rim in which the engaging sockets are larger.

The long arms 13 of the bars 1 and 2 serve as handles when the tool is being used, as shown in Fig. 1, one or both of these arms preferably terminating in sharpened portions 14 adapted to be inserted in a notch 15 in the run flange 20 to detach the same, as indicated in Fig. 4:, or to be used to lift a tire bead over the flange of a one piece rim, or in any other suitable manner. When the tool is used in this manner the bars are preferably separated, as indicated in Fig. 2, two tools or levers being thus provided. This is particularly desirable when using the tool to apply a tire to the ordinary one piece clencher rim as a pair of levers are necessary satisfactorily to perform that op eration.

Having thus described a preferred embodiment of my invention, but without desiring to limit myself to the precise details set forth and illustrated, I claim:

1. A tire tool comprising a pair of crossed bars pivoted together, one arm of each bar having projecting therefrom oppositely disposed studs of different diameters.

2. A tire tool comprising a pair of members pivoted together, each of said members carrying at one end a reversible plug having a stud projecting from each end thereof. 1w

3. A tire tool comprising a bar having reversible threaded plug screwed into each at one end thereof an eye and a reversible eye, and a stud projecting from each end of plug mounted in said eye, said plug having said plug.

a stud projectmg from each end thereof. EDWIN O. SHAW. 5 fl. A tire tool comprising a pair of bars Witnesses:
